Trait AssetData 

pub trait AssetData: DowncastSync { }

Trait for asset data that can be stored in an asset.

This trait extends DowncastSync to allow for safe downcasting to concrete types. Types must explicitly implement this trait to be used as asset data.

Implementations

impl dyn AssetData

pub fn is<__T: AssetData>(&self) -> bool

Returns true if the trait object wraps an object of type __T.

pub fn downcast<__T: AssetData>(self: Box<Self>) -> Result<Box<__T>, Box<Self>>

Returns a boxed object from a boxed trait object if the underlying object is of type __T. Returns the original boxed trait if it isn’t.

pub fn downcast_rc<__T: AssetData>(self: Rc<Self>) -> Result<Rc<__T>, Rc<Self>>

Returns an Rc-ed object from an Rc-ed trait object if the underlying object is of type __T. Returns the original Rc-ed trait if it isn’t.

pub fn downcast_ref<__T: AssetData>(&self) -> Option<&__T>

Returns a reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_mut<__T: AssetData>(&mut self) -> Option<&mut __T>

Returns a mutable reference to the object within the trait object if it is of type __T, or None if it isn’t.

pub fn downcast_arc<__T: AssetData + Any + Send + Sync>( self: Arc<Self>, ) -> Result<Arc<__T>, Arc<Self>>

Returns an Arc-ed object from an Arc-ed trait object if the underlying object is of type __T. Returns the original Arc-ed trait if it isn’t.
